METHOD FOR MANUFACTURING STRAINERS FOR WELLS. l

To all 'whom it may concern:

Be it known that I, FRED I. GETTY, a eitien oli the United States ofAmerica, residing at Jennings, in the parish of Calcasieu and State ofLouisiana, have invented certain new and useful- Inrprovements inMethods for Manufacturing Strainer-s for Wells, o'f which the followingis a specilication.

My invention'relates to a certain new and improved method formanufacturing strainers for wells, and its object is to provideI amethod for such manufacture which shall have certain advantages whichwill appear more fully and at large in the course et this specification.

The apparatus which I prcl'er to use in practicing my improved method isthat illustrated, described in detail and claimed in my application onmachines l'or immulacturing screening l'or well tubes, tiled on evendate herewith and, allotted Serial Number 253,18), and this preferredform of apparatus is ili'nsi' trated in the ata-.ompanying dii-wings, in

' upon the pipe to,center thcl l'rame.

which .Figure l is an elevation ol the apparatus; Fig. 2 is an elevationof the wire-forming rollsyFig. ii is a section in the line Ii olh Fig.2, Fif 4 is a section in the line il -4 of Fig. l.; Fi l. 5 is a topplan ol the apparatus, and Fig. t3 is a perspectiJe vView ol` a shortlength ol' the wire alter being passed through the wire-loruiing rolls`lt will be obvious that as iai' as the method oi'` operation isconcerned, any one ol' a large. number ol` devices ce.. he used and byillustrating in. detail the preferred torni ol' apparatus, lv do notintr ml to limit mysell to the use thereof.

ln l'orming tiltcrs or straim-,rs according to `my improved method, apipe, A, having 'perl'oiations, o, is lirst provided. 'lhis pipe iscentered in. a lathe, l), or other devicE by whichit can he rotated,:ind upon it is mounted a l'rame, (f, carrying rolls, c, c,aml shoes,ci, ci.

cated by, l), in the drawings, is in the lrst instance passed between.two l'orming rolls, lt), F, which have grooves, ,f, to receive the headol" the T. The groove, f, has notches or depressions, j", into which thematerial ol' the T-liead is crowded, so :is to l'orni laterally-projecting lugs, d. '.lhe depth ol' the deprcssiomj", determinesthe .size or height ol' the lugs, andv as will subsequently appear, themesh ol3 the screen and the l'orming rolls are therefore made readily'ren'iovablc l'rom place as simwn and described in my application abovereferred te, so that the apparatus can be readily adapted to themanufacture el' screening of 'various meshes.

After the wire leaves the l'orming rolls l'rom. which it emerges withone smooth edge and one tugged edge, it is wound upon the ii'ie, it, asillustrated, the lugs on one turn lying against the llat or smooth edgeon the next turn, thereby spacing the turns apart and forming meshesbetween the turns of wire through which lioruid can pass. lt will. beobvious that the size oli the mesh is determined by the height. olthelugs, d, l'ormed on the wire.

rl'he wire is drawn through the iorming rolls solelyY by means ol thepipe. and the entire l'raine. and forming mechanism is shil'ted alongthe pipe hy engmndnent ol" th'e shoe, el, with the hist turn oil 'thenire.

'The method herein set` i`ori`h is particularly advantageous for thereason that a uniform height, so that :i pcrl'ect screen can beobtained. Fiu'therznore, wil h the method herein pointed out, relisharing depressions ol various site. can be used, und inlerclmnged withcomparative ease, so that screens ol various mesh can be produced withthe .same apparatus. lerciolire, the. mien siveljiy used .aerei-n hasbeen a screen ce vposed olL oriimtry wire geen, und, :is :i

sult, the users oll :such screening have. come to identityy the lim-nessol' .scre n which the), desire, h i' the numher ol' the mesh olwirigauze hating correslminlingly lim` openings.

ln order to sell filters ol the type herein l shown on :i practicalcommercial scale, it is necessary, or at least extremelyv desirable, tobe ableI to'l'urnish them with meshes which correspond accurately to thestandard wire gauze meshes, and by the use ol curious interchangeablerollers, this can he done with the greatest. ease with my device.

l. realize that. coursiderubie rurialion is wire is ,'nod-uced havinglugs olA absolutel)r lil() strainen' which consists in forcing a Wirealo possible in the details of the procedure herein described, and I donot intend to limit 1nyself thereto except as set forth in the ciairns.

I claim as new and desire'to secure by Letters Patent l. The method ofmaking a Wire Wrapped through a lug-forming device, adapted to form ingsthereon by c'ornpression,"fthen winding that portion ofthe W1re u onwhich the lugs have been formed aroun a central core and keeping a.tension upon thel Wire during the entire lug forming and Windingoperation.

2. The method of making a wire Wrapped strainer, which consists indrawing a Wire throuvh a lug-forming device having a roll provi( ed witha depressioninto which the metal is forced to form the lugs bycompression, then winding that portion of the wire on which the lugshave been formed around a central core and keeping the wire lduring theentire operation under tension,

3. The method of making a Wire wrapped strainer, which consists indrawing a Wire throu h a 1n forming device having a roh provi ed Wit adepression into which the metal is forced to form the lugs bycompression, then winding that portion vof the wire on which. thelugs-have been formed around -a central core, the uli of the wire whichis necessary to draw 1t through the 1ug-forming devlce behig imparted tothe wire hv Winding that portion of the Wire n on which the 1u s havebeen formed arouni the core.

l. he method of making e Wire wrapped strainer. which consists indrawing a wire feeaeo through n lugorining device embodying a pair otreha' one ot which is provided With depressions lnto which the meta]A ofthe wire is compressed. to form ings, then Windhig ortion of the wire onwhich the luge l of the wire upon 'which the lugs have been formedaround the core.

5. The method of making a Wire Wrapped strainer, which consists indrawing a wire through a lug-forming device and which re duces the widthof the Wire, then winding that portion of the Wire Awhich has beenreduced in Width and on which the lugs have been formed around a centralcore with the transverse elements of the reduced Width portion extendingparallel to the axis of the core,`the null of the Wire which `ienecessary to draw it through the lug-forming device being imparted `tothe wire by Winding 'that portion o1 the wire 'so reduced and upon whichthe ings have been formed around. the core and Vkeeping e tension uponthe wire during the entire iugi`oir1iing and Winding operation.

in witness whereof I have signed the above application for LettersPatent at den Dinge, in thc parie-h. of Caicaeieu' and State ofliiouisiane, this 21st day of Maekrt. D. i905.
